'ments for couches, cots, beds and the'like;

and it is particularly directedtoresilient legs for ambulancecots designedfor use in I, the conveyance'of invalids V I Theobject of the invention is to provide means for couches andth'e like,-by which the top is resilientlysup ted so that jars and bouncing of the carriage in tra-nsport- 1 ing an invalid is not felt-by him. v

*The' invention consists in the novel con struction and arrangement of parts hGI'GlIl-i v a fter 'described and set forth in the claims.

Referring to the illustrative embodiment ofthe invention the top 1 of the couch upon which a person may be placed, may have any suitableform. The frame of the top inthe' present illustration is formed of tubes 21:0-

gether with suitable' cross-tubes to make it areT-unions?) intothe'lower openings of which arethr eaded or otherwise secured the sleeves 4Q WVithin each sleeve is a coiled spring the upper end ofwhich abuts the lower face of a plug 6 secured in or part'of the upper end of the sleeve. The lower end of the spring engages theupper end of a s leg 7, the upper end Sof the leg being rounded to fit within the sleeve and the lower, end: of the sleeve-being rounded inwardly after the head of the leg is. inserted in the-sleeve to prevent the unintentional withdrawal of the leg from the sleeve. A plug 9,- preferably formed of feltor some other substance adapted to take up oil, is insertedwithin', the lower end of the coiled spring and above the upper end o'fthe leg'7. oil hole 10 is formed in thesleeve adjacent the plug 9 through which oil may he admittedto saturategthe plug. This plug-therefore causes 7 a lubricationof the int-eriorof the sleeve.

s ocket l3 is formed in the lower end ofthe The lower end of the leg is inserted into aunion 11, atube 12 being connected to the ,unions' 11 on "each side of-the frame; A

At the opposite vends of each tube 2 nesting the two frames, each vertical memleg 7 for the reception of thespindle of the cast-or 15, a ball 16 being disposedlbetween the upper endoi' the spindle 14 and l the end offthe socket. A groove 17 r is" formed in the spindle'into which is project-f. edthe inner end of a set screw 18that isin v FRANK cHALrAnT, or Foam WAYNE, INDIAN serted through the wall of the union and the adjacentwall of the socketfl- It is ap I parent that the Isetgscrew prevents withdrawal ofthe leg 7 from the union'll and also-thefwithdrawal ofthe oastor l5 fromv I that union, but permits rotation of the spindlel l in'the socket. v 1 V. I It will be noted that thefleg below the upperend is less in diameter thansaid upper i end, This feature permitstlie-sleeve todescend. without binding, on the leg whenit may be-out of line with said leg by reason of an extra weight being applied to the top sudden jar on thedescend and compress t-he springs '5 more or less.
